Application filed July 7,

T 0 all whom it may concern:

Be it known that l, STEPHEN I. FEKETE, a citizen of Hungary, residin at Detroit, county oi Wayne, State of ichigan, have invented a certain new and useful improvement in Oil-Cups, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to oil cups such as are used particularly on the shackle bolts of an automobile chassis. An important object is to provide a cup of large. capacity adapted for use on horizontal shackle bolts to do away with the frequent refilling which has been necessary with the comparatively small cups now in general use. The oil cup shown in the present application is an improvement on the one shown in prior application, Serial No. 352,809, filed anuary 20, 1920, to which reference may be had for a fuller explanation of the purposes, mode of operation and advantages of oil cups of the type shown and broadly claimed therein. The particular object of the present invention is to provide a cup which will have all the advantages of the oil cupshown in my prior application and will be more certain in operation and betteradapted to be manufactured in large quantities.

The invention w1ll be fully understood from the following description when taken in connection with the accompanying drawings, and the novel features thereof will be pointed out and clearly defined in the claims at the close of this specification.

In the drawings, Figure 1 is a vertical section oi an oil cup embodying the invention.

Fig. 2 is a detail View of the oil feeding means and. the supporting disk therefor.

Fig. 3 is an end view of the parts shown inl ig. 2. Referring now to the drawings, the oil cup comprises the following parts :a stem '12, an end piece or bottom 19, a body or casing 13, a wick retainer 29, a baflie 40, an oil introduction tube 23, a valve 25, a spring '8 and wicking 30.

The stem 12 is adapted for connection with the part to be lubricated, and is screwthreaded as shown at 15, is shaped at 16 for the reception of a wrench,and is bored and counter-bored at 17 and 18 respectively to the outlet passage for the oil.

Specification of Itetters Eatent.

serial No. teases.

The body 13 is made from very thin material, such as sheet steel or brass, which is pressed or spun-into the desired form and is closed at one end with the exception of a ning the edge of the body over onto the edge of the end piece.

Secured tothe interiorof the casing as by brazing or soldering and surrounding the inlet opening 21, is an oil introduction tube 4 23. This tube extends inwardly and prevents the oil from splashing out of the inlet opening. It keeps the oil from running out when the cup is tilted by the movement of the vehicle to which it is attached. Adjacent the inlet opening 21 and within the oil introduction tube 23, the casing is formed into a valve seat 2 which cooperates with a valve 25 to close the said inlet opening. The valve is formed with a head 26 and a long stem 7 which extends through baflie 40, the wick retainer 29, the end piece 19 and intothe counter-bore 18 in the stem 12 of the casing. The valve is normallyheld against theseat 2 by a spring 8 coiled about the valve stem, one end of said spring engaging the head 26 of the valve and the other end I engaging the bafile 40 which itself rests against the wick retainer.

The oil feeding means consists of wicking, shown at 30, arranged in a series of strands so spaced inside the casing that the winking will always be immersed in the oil regardless of the position of the oil cup. These strands are held in place by the wick retainer 29, and their free ends 31 extend through the outlet opening in the casing. The wick retainer 29 is loosely mounted in the casing and comprises a disk 3 provided with a hole 33 located centrally thereof to allow for the passage of the valve stem, and holes 34 cut through the periphery thereof and spaced apart at intervals about the center. The disk 3 is also provided with legs which are struck up in forming the holes 36, and which contact with the end piece 19. I prefer to make the holes 34 of the form shown in the drawings so that the wicking can be put in place without threading it through holes.

The wicking is attached to the wick retainer 29 by insertion in the holes 3 1, as shown in Figs. 2 and 3, and the free ends 31 are'carried down between the fiat part of the disk and the adjacent side of the casing and into the counter-bore 18, which is large enough to contain the strands and the stem of the valve without jamming the wicking. The ends of the strands are then carried through the bore 17. The size of the bore 17 and the amount of the wicking employed are such that the bore will be completely filled so that free flow of the oil is prevented but is not filled full enough so thatcapillary flow is interfered with. I

The wick retainer serves to guide the valve stem. Both the wick retainer 29 and the baflie 40 are held in place by the valve spring 8.

In assembling the oil cup, the valve 25 with the spring 8 surrounding it is put inplace, then the bafiie 40 and wick retainer 29 are placed over the valve stem 7 and finallythe wicking pulled through the stem, the casing 13 and end piece 19 put together and the edge 22 spun into place to secure the whole together.

This construction is such that a minimum of operations isrequired in manufacturing the oil cup and it is not necessary to solder or braze the baflie or wick retainer in place.

What I claim is 1. In an oil cup, a casing having an inlet and outlet opening, an. oil introduction tube surrounding the inlet opening, a valve adapted to close the inlet opening, wicking in the casing extending into the outlet opening, and a wick retaining member having holes therein by which the wicking is held in position in the casing.

2. In an oil cup, a casing having an inlet and an outlet opening, an oil introduction tube surrounding the inlet opening, a valve adapted to close the inlet opening, wicking in the casing extending into the outlet opening, a wick retaining member loosely disposed in said casing and havin holes therein by which the wicking is hel and means for positioning said member in the casing.

3. In an oil cup, a casing having an inlet and outlet opening, aninwardly extending oil introduction tube surrounding the inlet opening, a valve adapted to close the inlet opening, wicking in the casing extending into the outlet opening, a loose wicking retaining member, and a valve ring, one end of which acts on the valve an the other end on the wicking retaining member to hold both members in position.-

4. In an oil cup, a casing having an inlet and outlet opening, an inwardly extending oil introduction tube surrounding the inlet opening, a valve having a stem and adapted to close the inlet opening, wicking in the casing extending into the outlet opening, a loose wicking retaining member having a hole forming a guide for the valve stem, and a spring, one end of which acts 6. In an oil cup, a casing having inlet and outlet opening, an inwardly extending oil introduction tube surrounding the inlet opening, a valve having a stem and adapted to close the inlet opening, wicking in the casing extending into the outlet opening, a 10 se wicking retaining member and a bafiie, eztchhaving a hole forming a guide for the valve stem, and a spring, one end of which acts on the valve and the other end on the wicking retaining member and baflle to hold said members in position.

7 In an oil cup, a casing having an inlet and outlet opening, an inwardly extending oil introduction tube surrounding the inlet opening, a wick retaining member having legs spacing it from the end of the cup, a valve and a spring acting on the valve and on the retainer to hold it in position with the legs against the end of the cup.

8. In an oil cup, a casinghaving inlet and outlet openings, a wick retainer to hold the wicking in radial arrangement rtlatively to the outlet opening, and having holes arranged about its periphery to receive the wicking, and wicking in said holes and exv ing, means for positioning said wick retainer in said casing, and wicking in said holes and extending into the outlet 0 ning.

In testimony whereof I a x my signature.

STEPHEN I. EEKETE.
